ABSTRACT:
In a method for producing an L-amino acid by culturing a microorganism having an ability to produce an L-amino acid in a medium to produce and accumulate the L-amino acid in the medium and collecting the L-amino acid from the medium, a Gram-negative bacterium having the Entner-Doudoroff pathway and modified so that 6-phosphogluconate dehydratase activity or 2-keto-3-deoxy-6-phosphogluconate aldolase activity, or activities of the both are enhanced is used as the microorganism.
